Abstract (en)
[origin: EP2241938A1] An image forming apparatus for detecting surface conditions of a recording sheet on which an image is formed, includes a light source (42A,42B) that emits a first light beam and a second light beam, an image capture device (43A,43B) configured to capture a first image of the surface (44SA,44SB) of the recording sheet illuminated with the first light beam and a second image of the surface of the recording sheet illuminated with the second light beam. A straight line including a ray in a center of the first light beam and a straight line including a ray in a center of the second light beam intersect with each other, when each straight line is projected on the surface of the recording sheet, and information about the unevenness on the surface of the recording sheet is detected based on the first image and the second image.
